Product Description

Consealed fire door drop down seal  M-type spring structure, suitable for doors with slots in the door leaf. During installation, there is a 34mm*14mm through slot at the bottom of the door. Place the product in it, fix it from the wing of the product, and install the decorative end cover with screws. The use of this product does not affect the overall style of the door.

When a fire occurs, the fireproof expansion seals on the wings installed on both sides will expand rapidly to block the gap at the bottom of the door, prevent the spread of flames, cut off harmful gases, fight for escape and rescue time, and provide a guarantee for the safety of life. In normal conditions, it can be used for sealing functions such as temperature insulation, sound insulation, and dust blocking.
